BARTHOLOMEW BROOKS, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO JOSEPH R. C. MCALLISTER, OF SAME PLACE.

AWNING.

SPECIFICATION forming part of Letters Patent No. 478,842, dated July 12, 1892.

Application tiled September 30, 1891. Serial No. 407.258. (No model.)

To @ZZ whom -it may concern.'

Be it known that I, BARTHOLOMEW BROOKS, a citi7.en of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and use! ful Improvement in Awnings, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to improvements in awnings; and it consists, first, of means for automatically raising the awning-frame.

It further consists of means for holding said frame at any angle or elevation desired.

It further consists of a support forming a guide for the awning-frame in its raising and lowering.

It further consists of the combination of parts hereinafter set forth.

In the drawings, Figure l representsa perspective view of an awning-frame embodying my invention, the covering being in dotted lines. Fig. 2 represents a side viewr of the same, with portion of the window-frame.

Similar letters indicate corresponding parts in the different figures.

Referring to the drawings, A represents the main frame of the awning, formed of wire or piece of suitable material, having loops or hooks B at its ends, whereby it may be pivotally secured to the eyes C, which are fastened to a suitable portion of a window or door frame D, over which the awning is suspended. To normally keep the awning-frame in a raised condition, springs are employed, each of said springs being secured at one of its ends to the frame D and at the other end provided with aloop F, which embraces and is movable on a side bar or portion ofthe frame A. A covering G, of any suitable material, is secured to the window-frame D and frameAin such manner as to be adapted to be raised or lowered by the movement of the said frame A.

Tokeep the frame A at any angle desired, so as to regulate the light entering the window or door on which the awning is placed,v the rods or supporting-arms I-I are employed. Each of the said rods is pivotally secured at one end to the frame D in line with the side portions of the frame A and below the same, the other end having a looped portion J, which embraces the side portions of the frame A and has journaled thereon a weighted or gravitating pawl or dog K, the upper end of which in normal position engages or contacts with the side portions of the frame A, so as to 5 5 force the said side portions into close contact with the loops J of the rods H, and thereby lock the same with the said rods H, preventing the further movement of the said frame, thus holding the awning in xed position. A 6o cord L, attached to the upper part of each of the pawls K, serves to release the pawl from engagement with the side portions of the frame A, thereby permitting the raising of the awning by means of the springs B. By pulling on the cords L when the awning is raised p releases the pawls and causes the looped portion J to bear on the side portions of the frame A, so as to lower the same to any position desired, when by releasing all tension or hold 7o of the cords the pawls K quickly engage the said frame A, so as to hold it at the elevation required. It will be noticed that when the pawl K engages the frame A the rods H receive the weight of the awning, supporting the same, and that when the frame is raised or lowered the side portions or bars thereof are guided in the looped portion of the rods H, so there is no twisting or side motion of the awning. o

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is-

l. In an awning, the combination of a pivoted awning-frame, a pivoted support therefor having an end thereof engaging a side of said frame,a weighted locking-dog carriedby said support to engage said frame, and a retractile spring connected with the side bar of the frame, substantially as described.

2. In an awning, a pivoted awning-frame, a pivoted supporting-rod havingalooped end adapted to embrace a side of the frame, a weighted dog pivoted to said rod and having a serrated upper end bearing against said side 95 of the frame, and a cord for operating said dog, said parts being combined substantially as described.
